What is ISO 2039-2 – Determination of Rockwell hardness of plastics about?

ISO 2039 is a standard that discusses plastics and the determination of its hardness.

ISO 2039-2 is the second part of the ISO 2039 series that discusses the Rockwell hardness of plastics. ISO 2039-2 specifies a method for determining the indentation hardness of plastics by means of the Rockwell hardness tester using the Rockwell M, L and R hardness scale.

For materials having high creep and recovery, the time-factors involved in application of the major and minor loads have a considerable effect on the results of the measurements.

Ideally, Rockwell hardness numbers should lie between 50 and 115; values above this range are inaccurate and the determination shall be repeated using the next severest scale.

Who is ISO 2039-2 - Determination of Rockwell hardness of plastics for?

ISO 2039-2 on determination of Rockwell hardness is relevant to:

Plastic industry
Plastic material manufacturers and suppliers
Product designers/product development teams
Quality control and testing authorities

Why should you use ISO 2039-2 - Determination of Rockwell hardness of plastics?

Rockwell hardness number is directly related to the indentation hardness of a plastic material. The higher the Rockwell hardness number, the harder the material.

ISO 2039-2 walks you through the method to accurately determine the Rockwell hardness number.

By adopting the test method, you can determine whether or not your plastic materials can withstand the stress and pressure during its use in end-applications. Thus, the Rockwell hardness number evaluates the plastics resistance to penetration or indentation.

As a result, ISO 2039-2-compliant methods to determine the Rockwell hardness number can play a significant role in minimizing the risk of product failures. Moreover, this assessment can make a positive contribution to your product development initiatives, such that the plastic used is fit for its intended purpose.
